OpenGL shader extension not available

[san]

how to fix this problem

Warning: OpenGL shader extensions not available.
		 This is a limitation of your video card
		 or driver, and will prevent Houdini from
		 using GLSL shaders.
		 Set the HOUDINI_OGL_ENABLE_SHADERS
		 environment variable to zero to avoid
		 attempts to use this extension.

It's just a warning that your graphics card doesn't support the extension. You can continue to ignore the warning or set the HOUDINI_OGL_ENABLE_SHADERS environment variable to 0 and you won't get the warning again.

Cheers!

where and how to set that variable to 0 ?

Not sure which version & OS you using but in your $HOME/houdini9.5 or $HOME/houdini10.0 directory, there is a houdini.env file. You can edit that file with a text editor and do the following:

#
# Houdini Environment Settings
#
# The contents of this file are read into the environment
# at startup.  They will override any existing entries in
# the environment.
#
# The syntax is one entry per line as follows:
#	VAR = VALUE
#
# Values may be quoted
#	VAR = "VALUE"
#
# Values may be empty
#	VAR = 
#

# Example:
#
# HOUDINI_NO_SPLASH = 1

HOUDINI_OGL_ENABLE_SHADERS = 0

If you don't have the houdini.env file, you can copy & paste the above into a file named "houdini.env" and place it in your $HOME/houdini9.5 or $HOME/houdini10.0 directory.

Cheers!
